Technical Field
The invention relates to application of acanthopanax giraldii harms leaves and an extract thereof in preparing anti-fatigue medicines or health-care foods.
Background
Fatigue is a complex physiological and biochemical change process of an organism, and refers to a normal physiological phenomenon which is necessarily caused when mental or physical strength reaches a certain stage. It marks a temporary decline in the body's original working capacity and may be a precursor to the body's development of a disease state. The fifth international biochemical conference on exercise in 1982 unifies the concept of fatigue, in which physiological processes of the body do not continue its function at a specific level or the organs do not maintain a predetermined exercise intensity. Fatigue can be caused by any change in the metabolism of the substance from the central nervous system to skeletal muscle cells to the inside of the cells, in any intermediate stage or in a combination of stages. According to WHO investigation, more than 35% of people in the world are in fatigue state, and the fatigue state of middle-aged male population reaches 60%. Fatigue can cause reduced exercise capacity, reduced work efficiency, increased error accidents, and reduced combat effectiveness. If the fatigue can not be recovered in time after the occurrence of fatigue, the fatigue can be gradually accumulated to cause ' overstrain ', Chronic Fatigue Syndrome (CFS), overtraining syndrome ' and the like, so that endocrine disturbance and immunity decline of the organism occur, even organic diseases occur, and the health of human beings is threatened.

3 Experimental methods
3.1 Normal temperature load bearing swimming test of mice with different extraction parts of Acanthopanax giraldii harms leaves
Taking 60 mice with half of male and female, placing in an animal house for 3d to adapt to the environment, layering according to body weight, and randomly dividing into six groups, namely a blank control group, a rhodiola rosea extract group (positive drug group), a high and low dose group of acanthopanax giraldii harms leaf water extract, and a high and low dose group of acanthopanax giraldii harms leaf water extract alcohol precipitation solution. Respectively performing intragastric administration with 0.2mL/10g/d of distilled water, rhodiola rosea extract and medicinal solution with corresponding dose. The dose and concentration are shown in Table 1. Continuously performing gastric lavage for 6 days, fasting before the last administration for 12h, and 30min after the last administration, putting the mouse into a water pool with water depth of 20cm and room temperature, and recording the time from the beginning of swimming to the exhaustion of the physical strength of the mouse (the head of the mouse is immersed in water for 10S and cannot float out of the water surface, so that the physical strength is exhausted).
TABLE 1 Experimental drug dosages and concentration tables
Figure BDA0001070959030000041
3.2 statistical methods
Data were analyzed with SPSS16.0 statistical software, all indices are expressed as mean ± standard deviation, and differences between groups were compared using one-way analysis of variance.
4 results of the experiment
4.1 Normal temperature load bearing swimming test of mice with different extraction parts of Acanthopanax giraldii harms leaves
Compared with the blank control group, the low dose of the rhodiola rosea and acanthopanax giraldii harms leaf water extraction and alcohol precipitation liquid can obviously prolong the time (P is less than 0.05) of the exhaustion of the mouse weight-bearing swimming physical strength, and the high dose of the acanthopanax giraldii harms leaf water extraction and alcohol precipitation can obviously prolong the time (P is less than 0.01) of the exhaustion of the mouse weight-bearing swimming physical strength. The water extract of the acanthopanax giraldii harms leaves has the tendency of prolonging the physical exhaustion time of mice in load swimming, but has no statistical significance (P is more than 0.05) (see table 2). There is a certain dose-effect relationship between dose and effect, and the high dose group has good effect in the lower dose group.

Figure BDA0001070959030000043
Note: p < 0.05, P < 0.01, compared to the blank control group
4.2 discussion and conclusions
The research shows that different extraction parts of the acanthopanax giraldii harms leaf skin can prolong the time of heavy swimming of a mouse, wherein the effect of high dose of the water extraction and alcohol precipitation liquid is the best, the effect of low dose of the water extraction and alcohol precipitation is the second, and the water extraction liquid has a prolonged trend and is in a certain dose effect relationship.
The experimental result shows that the acanthopanax giraldii harms leaves and the water extraction and alcohol precipitation liquid thereof have obvious anti-fatigue effect.
In conclusion, the acanthopanax giraldii harms leaf and the extract can effectively prolong the time of mouse weight swimming, have the anti-fatigue effect and have good application prospect.
